PRE - INSTALLATION INSTRUCTIONS
¾ Prior to the installation and start up of your new TK SERIES cooling tower
water treatment system, the following cooling system preparation instructions
should be followed.
A) Carefully inspect the cooling tower and reservoir for any algae growth, which might
be present. If algae is present, completely remove and clean all surfaces before
installation and start-up.
¾ Cleaning and removing existing algae growth may require shocking the
cooling system with a strong algaecide and manually scrubbing all surfaces
where algae have established a base growth. A cover for the cooling tower
distribution pan or shading of areas exposed to direct sunlight is
recommended.
B) Disconnect and remove all treatment chemical drums and metering pump feed
systems.
C) Draining the pump tank and refilling with fresh water, is the preferred method of
elimating the residual chemicals in the cooling system. If this can not be
accomplished you should discontinue the use of all chemicals at least 5 days prior to
starting the TK Series system and increase the blow down to purge the system of
chemicals.
D) Inspect the cooling system for heavy scale deposits. These deposits should be
removed prior to the start up of your
TK SERIES system. The TK SERIES system
will remove the old scale. More frequent cleaning of strainers be may necessary.
